       While running the shell script, if we get "Permission denied" message we should give executable         permission to the file.

• Example

      We can provide the executable permission by using the below command,

      chmod +x filename.sh.

      chmod (Change Mode) - Using chmod we can change the access permissions to file system    objects.

+x - It makes the file executable.
